Environmental information

What is Access to Information on the Environment (AIE)?

Information relating to the environment held by, or for, a public authority must be made available on request to any person, subject to certain exceptions.

The European Communities (Access to Information on the Environment) Regulations 2007 to 2018 provide a definition of environmental information and outline the manner in which requests for information may be submitted to public authorities. The Regulations also provide for a formal appeals procedure in the event that a person is unhappy with a decision on their request. You can view an unofficial consolidation of the Regulations on this website.

Frequently Asked Questions

What is the difference between AIE and Freedom to Information (FOI)?

The Access to Information on the Environment Regulations operates in parallel with the Freedom of Information Act 2014. While the two legislative codes are broadly similar (with respect to environmental information), the AIE Regulations and the FOI Act differ in that a wider range of public authorities are covered by the AIE Regulations than by the FOI legislation. There are also material differences in the grounds under which access to information can be refused under the two legislative codes.

What public authorities are subject to AIE?

Under the 2011 Regulations, the Minister is required to publish an indicative list of public authorities that are subject to the AIE Regulations. These are:

  1. Government Departments e.g. the Department of Environment, Community, and Local Government
  2. Local authorities e.g. Cork County Council
  3. Non-commercial state agencies e.g. the Environmental Protection Agency
  4. Commercial state agencies e.g. EirGrid
  5. Regulatory bodies e.g. the Commission for Energy Regulation
Is there a charge for submitting a request for information under the AIE Regulations?

There is no initial fee required when lodging a request for information under AIE.

Is there a charge for the supply of information under the AIE regulations?

In line with the regulations, a public authority may charge a reasonable fee for supplying environmental information in accordance with the Regulations.

This fee will be calculated upon receipt of a request, and is calculated according to the volume of work involved in compiling information where it has not been previously available in an accessible format. This fee is €20 per hour.

If requesters require hard copies, a fee of 4c per sheet will apply. If requesters require CDs, a fee of €10 per CD will apply.

Requesters will be informed in writing of the fees involved, on receipt of their request, and a 20% deposit will be required to be paid to the National Transport Authority (NTA) before commencement of the work involved. The requester has an opportunity to review or amend his/her request at this stage. The process will not commence until the deposit has been received by the NTA. It should also be noted that the date for the final decision on the AIE request (which is normally within one month of the NTA receiving the request) will be determined by reference to the date the deposit payment has been received.

The balance of the fee will fall due when the information requested has been compiled and copied, and before it is released to the requestor.

The NTA has committed to ensuring that the charging of this fee will not, as a general rule, exceed the actual costs of producing the material in question.

How will the National Transport Authority supply information free of charge?

It should be noted that fees in respect of supplying information may be waived where the cost is estimated at less than €10.

Where requesters are in a position to view the required documents on site at the NTA offices there will be no charge for accessing these records; however, this is separate to the charge noted above.

Electronic access can be provided to requesters free of charge via email; however, this is separate to the charges noted above.

How do I make an AIE request?

Applications under the AIE Regulations for environmental information should be made in writing. The request should:

  • State that the application is being made under the Access to Information on the Environment Regulations 2007;
  • Clearly indicate the specific environmental information required, and the preferred form and manner of access desired, and
  • Provide contact details.

Once completed you should send your AIE request to the NTA:

By email aie@nationaltransport.ie
By post Information Officer,
AIE Unit
National Transport Authority
Dún Scéine,
Harcourt Lane,
Dublin 2
D02 WT20


Normally, decisions on requests made under the Regulations are notified within one month of their receipt by the NTA.

What can I do if I am unhappy with a decision on my request?

If you consider that your original request for environmental information was refused wholly or partially, or was otherwise not properly dealt with in accordance with the provisions of the AIE Regulations, you may, no later than one month after receiving the decision, request the NTA to carry out an internal review of the decision in part or in whole.

No fee will be charged for the internal review process.

A written outcome of the review informing you of the decision, the reason for the decision and advising you of your right of appeal to the Commissioner for Environmental Information, including the time limits and fees associated with such an appeal, will be issued to you within one month of receiving the request.

How do I make an appeal to the Commissioner for Environmental Information?

A written appeal should be submitted to the Commissioner for Environmental Information:

Through their website https://www.ocei.ie/en/collection/fc0ff-make-an-appeal/#make-an-appeal-online
By post Office of the Commissioner for Environmental Information (OCEI)
6 Earlsfort Terrace
Dublin 2
D02 W773


The AIE Regulations require a fee of €50 for an appeal to the Commissioner for Environmental Information. However, provision is also made for a reduced appeal fee of €15 for medical card holders, their dependents and also for people, not party to the original request for access to information, that are appealing a decision to release information which they believe will affect them.

Further contact details and information on the Commissioner’s Office are contained on the Office of the Commissioner for Environmental Information (OCEI) website. You can also telephone the OCEI on 01 639 5689.
